Hello every one,
About a week ago I accidentally dropped my galaxy s7, although there were no visible damage to front and back but just after that I realized that my wifi range has become very weak.
I'm able to connect to my router if I stay close to it, but as soon as I starts moving away signal drops dramatically. This was not the case before my phone was dropped.
Someone told me that may be wifi antenna connection is loose.
So today I decided to open my s7, I successfully open the back cover but now I have no idea where the wifi antenna is. I search over the Internet some page says the antenna is at the top some says they are at the bottom.
So can anyone please tell me the exact location of where the wifi antenna is in galaxy s7.
It would be great if you can share images of that portion.
Thanks
That's the kind of infos to look for BEFORE opening a phone, don't you think?
Well, after some search, it seems that when you open the back cover of the S7, at the top of the phone, you have some kind of black plastic plate with metal parts in it, and there is another one at the bottom of the phone. The one at the bottom seems to include the speaker.
Both top and bottom parts are antennas, but my guess is that, due to the position of the phone when holding it for a phone call, they probably have tried to put the phone network antenna as far as possible from the head.
So I would say the top part is the Wifi antenna and the bottom part should be the phone network antenna.
Also, from my searches, it is said on different places that this top "black plastic plate with metal in it" which should be the Wifi antenna, is kind of weak and we have to be very careful when dismantling it. So it is possible that it broke when you dropped your phone.
Sorry, that's all I can do for you, nothing is sure as even in spare part, they only talk about "internal antenna" without specifying Wifi or not.
Even if it's for S7 edge, in your S7 you're looking for a part at the top of the phone that looks like this: https://stellatech.com/en/samsung-sm-g935f-galaxy-s7-edge-antenna-module,a,823480.html/
I've got exactly the same problem.
Did you find a fix?

forgive me if it has been posted over and over again, but after some time now, has any1 actually found a real fix? from last year's thread till now, some say it's software some say hardware, some say hard case solves it but some says aluminium foil does it. some even say by simply turning on best wifi performance, it will solve it.
some others say flashing a custom rom fixes it. so what is the actual fix? tomoro im going to buy aluminium foils and run it all over the antennaes behind my back cover and see if it helps..
i've tested my sensation, yes death grip is there, but not as terrible as people had it before.
here's my test results :
ROUTER : ASUS N53SV (use connectify)
OS : WIN7 HP
distance from router, 2metres, but blocked with a wooden door (those thick and hard type).
normal holding position : full bar
cover the antennae : 4 bars (- 1 bar)
cover the antennae with 2 hands : 3~4 bar
scenario 2 : distance : 10 metres (blocked by walls and doors) (went to different room on the same floor
normal holding position : 4 bar
cover with 1 hand : 2 bar
cover with 2 hand : 1 bar
considering the fact that im using my laptop to emit wireless signal, this is not bad at all. but im still trying the aluminium foil fix tomoro. will report back
do post your methods of fixing here if you have it thx
Every smartphone has a deathgrip issue and to be honest, it doesnt affect me so much. When i cover with my hand the antenna positions, signal drops 1 line, maximum 2, but like i said, that's normal. Had this problem with 3 different phones, and i think its a general smartphone issue. In many cases people like overreacting.
But hey, thats my opinion!
i've tried my damndest to find this death grip and i just cannot...i run a speedtest and completely cover every single part of the phone with both hands and i still manage to get a 10Mb throughput...so i just don't get it
Have you got a dual band router, if so that's probably why you cant find it.
Death grip affect all of the Sensation phones whether people admit it or not. The back cover is part of the antenna, so covering it with your hand WILL drop the signal. I find it is worse with wifi. No software will fix it, no tinfoil will fix it, no ROM will fix it. Just don't clasp your hands fully around the back cover and its not a big problem.

that said, some people dont experience it at all. there's a couple of youtube videos proving that. they cover the entire backside of their phone and there's no signal loss..
Hello Guys,
I was loking for hours to find Aluminum Covers for the DHD to replace the plastic parts but wasn't able to find them (if they even exist).
I only know that HTC never officially released them.
But since I saw the MAO Method they used on the One S I wanted the same for my DHD
Does anyone know a shop where I can find these covers made of aluminum?
Thanks

You mean the doors? Won't find them because the clips to hold them in place wont function being made out of aluminum. Thus why only the immobile parts are made of it. If that is not what you are talking about, ignore me Not to mention the signal loss of grounded aluminum over the antennas would be crazy.

But would't it be possible to make the outer part of aluminum and just the clips of plastic?
But ok seems to be impossible sad to hear

possible yes, but the biggest factor would be that each plastic door covers an antenna. the led flash covers the gps, the battery covers the wifi, and the bottom door covers your cellular antennas. So replacing those with any kind of metal would connect them to the outer shell and ground them, almost completely shielding your phone from signal.
I just looked at the antenna except of gps (didnt want to open it all up). Wifi is just simply spaned mabe same with GPS. Only antenna that runs a bit through the door is the Sim/SD Door Antenna but if you would take a pretty flat and small cable you could run it through the left hole beside the two connectors. I dont know much about antennas but this could even make a stronger signal doesnt it?
p.s. The hole i mean is a bit upper left the two connectors (phone up side down)

the simple answer is no. antenna length is specific to the frequency it uses.
I understand you need a specific lenght of the antenna for certain frequenzies. So the cable that would be needed to connect the two connectors should have around the same lenght as the the Antenna in the plastic door.
Do you know how accurate this would have to be and how do they realize to use different frequenzies with one antenna GSM around 900 MHZ and WCDMA around 2,1 GHZ?
Anything can be done the real question is how much are you willing to spend?
And is it really worth the trouble to go through trying to fix it?
You should just get a new phone instead of changing the parts.
Hi, I have a HTC ONE S. I recently dropped the phone from waist high.
Ever since, the phone been having spotty connection.
My SIM card is fine because i tried it in another phone.
I called TMOBILE and it is not on their end.
I am sure its a hardware problem.
How would I find the internal GSM Antenna Cable to make sure its connected right? I saw a video on how to disassemble the phone but it does not show where the Antenna is.
Please help.

Pop off the bottom plastic cover and look at the metal terminals that connect the mainboard to the inside of the plastic cover which is essentially the antenna. Do the same with the top cover. Behide the top cover here's six terminals in total to, the left, right, and above the camera. I don't remember how many there are behind the bottom. Take a small screw driver or toothpick or tweezers etc and push the terminals outwards from underneath (gently) so that they stick out more. Then replace your covers and see if that helps.

THanks. Ill try that and update you. Im at work right now. Ill try when i get home.
I decided to look into the GPS antenna issue since I was just not getting any lock... despite trying all sorts of software fixes. I also didn't fancy the idea of scraping anything :/
Anyway, too the back off the phone to have a look at the contacts, and below is a pic of what I saw.
You can see there are two contacts.
The top is signal, and touches the antenna.
The bottom is ground (continuity checked against the PCB ground plane) and as you can see that part of the antenna is painted.
I'm thinking we may be able to make use of this info.
I've tried to find out online where the antenna is located for the Xperia Z3. Closest I could get to is some pictures, BUT I don't know what's what in the photos...So
Can anyone please let me know where the location of the antenna is on the Xperia Z3?
This will also answer another question I've seen around - will a border / bumper case (so it doesn't cover the back, just the edges of the phone) made of aluminum ruin the reception quality on the phone?
- if the antenna is on the sides of the phone - more than likely, yes
- if the antenna is inside the phone at the back, no.
An extra, anyone else impressed with the reception of the phone? Above and beyond anything I've used before.
Cheers!

This'll be too late for u but may help some other poor bugger.
There are 5 antennas if you count the wifi cable.
1. WiFi cable. Left hand side where mag charge is.
2. Wifi/blu aerial left hand side next to usb
3. Gsm/4g aerial bottom behind mic
4. Nfc aerial on back of rear battery cover where nfc logo is printef
5. Sub aerial Top of fone behind speaker.
All are located behind battery cover. I have no idea what the sub one does. Maybe someone will tell us Source: Me (i replaced my screen and broke the main aerial in the process).
